Oxidation of Zirconium and Zirconium Alloys

Fate of hydrogen upon oxidation of zirconium alloys by water: Mechanistic insights from first principles calculations

Polyvinyl chloride (PVC) is one of the world’s most widely produced polymers and it is used in a wide range of areas such as building, transport, packaging, electrical/electronic and healthcare. Manufacturing of PVC products is dependent on several additives, e.g. plasticizers, heat stabilizers and flame retardants. To reduce the migration of additives in PVC products the incorporation of a nan...

Understanding Hydrogen in Zirconium

Selected examples of the Canadian contribution to the development of understanding of the behavior of hydrogen in zirconium alloys are reviewed. To solve the technical problems faced by the nuclear industry, it was necessary to have values for the solubility and diffusivity of hydrogen in the alloys, the diffusivity needed for the three gradients of concentration, temperature, and stress. With ...

Preparation and Characterization of Tetragonal Zirconium Oxide Nanocrystals from Isophthalic Acid-Zirconium(IV) Nanocomposite As a New Precursor

In this study, isophthalic acid-zirconium(IV) nanocomposite has been prepared from zirconyl nitrate pentahydrate and potassium iodide, with isophthalic acid, (C8H6O4=Benzene-1,3-dicarboxylic acid) as a ligand, via sonochemical method in ethylene glycol and methanol as solvents. The crystalline tetragonal ZrO2 has been produced by thermal decomposition of isophthalic acid-zirconium(IV) nanocompo...
